Capability

Something here.

Classes

class capability.Capability

_zIndex

Capability functions are ordered by this attribute.

class capability.Collector

capabilities

A list of Capability derived classes that are in the inheritance graph.

__init__()

At initialization time the collector searches through the inheritance graph and builds the list of Capability derived classes and then calls the __init__() method for each of them.

capability_functions(fn)

Parameters:fn (string) – name of a capability function

A generator that yields all of the functions of the Capability classes with the given name, ordered by z-index.

add_capability(cls)

Parameters:cls (class) – add a Capability derived class

Add a Capability derived class to the method resolution order of the object. This will give the object a new value for its __class__ attribute. The __init__() method will also be called with the object instance.

This new capability will only be given to the object, no other objects with the same type will be given the new capability.

_search_capability(base)

This private method returns a flatten list of all of the Capability derived classes, including other Collector classes that might be in the inheritance graph using recursion.

Functions

capability.compose_capability(base, *classes)

Parameters:

• base (Collector) – Collector derived class
• classes (Capability) – Capability derived classes

Create a new class composed of the base collector and the provided capability classes.

capability.add_capability(base, *classes)

Parameters:

• base (Collector) – Collector derived class
• classes (Capability) – Capability derived classes

Add a capability derived class to a collector base.

Note

Objects that were created before the additional capabilities were added will have the new capability, but the __init__() functions of the classes will not be called.

Objects created after the additional capabilities were added will have the additional capabilities with the __init__() functions called.
